Problems solved by technology

[0002] Rubber oil is an item that improves the elasticity, flexibility, ease of processing, and ease of mixing of rubber. Rubber oil is not only a softener, but it requires itself to have good compatibility and affinity with rubber. In the process of improving rubber processing, it can reduce the consumption of mixing power, promote the uniform dispersion of various auxiliary materials, and improve the elongation, resilience and other technical properties of vulcanized rubber. Anti-aging, this is its main mechanism. During the use of rubber oil, since rubber products are mostly exposed to sunlight, rubber oil is easy to age and lose luster, so the appearance of rubber products in use is not very good. OK, leading to poor user experience

Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] like figure 1 Shown, a kind of environmental protection type naphthenic rubber oil preparation method comprises the following steps:

[0020] S1. Crude oil mixing stage, mix naphthenic crude oil and solvent evenly, control the temperature between 400-650 degrees Celsius, then continue to add additives, plant asphalt, antioxidants and stabilizers, continue mixing, and control the mixing temperature at 80-650 degrees Celsius Between 150 degrees Celsius;

[0021] S2, the stage of standing crude oil, it is easy to stand still the crude oil obtained in the previous step, the standing time is between 20-30 hours, and the temperature is kept constant during the standing process;

[0022] S3, the crude oil extraction stage, the solution obtained ...

Abstract

The invention discloses a preparation method of environment-friendly naphthenic rubber oil. The method comprises the following steps: a crude oil mixing stage, a crude oil standing stage, a crude oil extraction stage, a hydrofining stage and an extraction separation stage. According to the invention, through the steps, polystyrene and an antioxidant are added into crude oil, so that the extracted rubber oil is more excellent in oxidation resistance, the rubber product can have better oxidation resistance under long-term exposure to sunlight, and the aging resistance of the rubber product becomes more excellent; the rubber oil has a better gloss effect through the arrangement of structures such as polystyrene and the like, so that the gloss effect of the rubber product is more excellent; and by matching the added antioxidant, the rubber oil has better anti-aging performance and gloss effect, so that after a user uses a rubber product added with the rubber oil for a long time, the appearance effect of the rubber product is more comfortable, and the use feeling is provided for the user.

Description

technical field [0001] The invention relates to the field of preparation methods, in particular to an environment-friendly preparation method of naphthenic rubber oil. Background technique [0002] Rubber oil is an item that improves the elasticity, flexibility, ease of processing, and ease of mixing of rubber. Rubber oil is not only a softener, but it requires itself to have good compatibility and affinity with rubber. In the process of improving rubber processing, it can reduce the consumption of mixing power, promote the uniform dispersion of various auxiliary materials, and improve the elongation, resilience and other technical properties of vulcanized rubber. Anti-aging, this is its main mechanism. During the use of rubber oil, since rubber products are mostly exposed to sunlight, rubber oil is easy to age and lose luster, so the appearance of rubber products in use is not very good. Well, it leads to poor user experience. Contents of the invention [0003] The main...
